    AbstractBackground and Objectives: Cesarean scar pregnancy (CSP) represents a type of ectopic pregnancy in which the embryo implants inside the scar of a previous cesarean section. This condition can lead to maternal morbidity and mortality. The best therapeutic approach in terms of clinical effectiveness and patient safety for CSP has not been described yet, although different therapeutic strategies are currently available. The purpose of the present study was to analyze the success rate of two different treatments in a single institution. Materials and Methods: A retrospective study was performed among patients diagnosed with CSP at the Gynecology and Obstetrics Department of the "Cannizzaro" Hospital in Catania (University of Enna-Italy) from January 2016 to December 2022. The diagnosis was made by 2D/3D transvaginal ultrasound, following Timor-Tritsch criteria. Two treatment strategies were performed: local and systemic methotrexate (MTX) injection and uterine artery embolization (UAE) with subsequent dilatation and curettage (D&C). All treated women underwent subsequent clinical and sonographic follow-up. Complete recovery was defined as the reduction of β-HCG values until it was undetectable and the disappearance of the mass in the uterine scar on ultrasound. Results: Nineteen patients were included; nine were in the MTX group and ten were in the UAE + D&C group. No significant differences were found between the two groups in terms of clinical parameters. Treatment was successful in 4 of 10 (44%) patients in the MTX group and 10 of 10 (100%) in the UAE + D&C group (p = 0.01); the length of hospital stay was significantly shorter in the latter group (p < 0.0001). Conclusions: In our experience, administration of MTX is not recommended as the primary treatment or pre-treatment. Dilatation and curettage after uterine artery embolization are better than methotrexate injection for the treatment of cesarean scar pregnancy in a single-institution series in terms of complete recovery and length of hospital stay.
